Mail Server v.1.0.7.7 is now out.

There are no changes in Web Interface.

Previous version (1.0.7.6) of mail server caused problems with users, who had SImple SMTP option disabled on the Options - Server Options - SMTP page. This version fixes the problem.

Mail Server

• Improved handling of lenghty SMTP connections. New method should eliminate problems with "stuck" SMTP connections, which waere causing high CPU load and, eventually, server crash on heavy loaded servers;
• Now individual domain groups can be exported and imported. Useful when splitting server between several computers;
• Fixed several minor problems;

Web Interface

• Fixed several problems with displaying complex messages on the web interface;

Mail Server

• Hopefully fixed a problem which was causing mail server to stop

Web Interface

• Web interface now will work with Safari;

Mail Server

• SMTP now supports two methods of authentication: AUTH PLAIN and AUTH LOGIN;
• Improved the way how "stuck" delivery threads are getting cancelled. In some cases with previous versions they could stay connected infinitely long;
• If a domain is in greylisting exception, and SPF is PASS, DNSBL will be not checked - to avoid blocking messages, when single IP addresses belonging to large ISPs are blacklisted by DNSBL databases;
• Now there is an option to check all IP addresses, referred to in RECEIVED headers, against DNSBL databases;
• If autoresponder is enabled, and return address is not specified, now the server will use username, plus @ symbol, plus either the first domain in the list belonging to the domain group, or domain group name itself;
• If SMTP for account is disabled for an account, connection will be still accepted, if it comes from web interface;
• If there is an unsuccessful attempt to log into the POP3 or IMAP server, or perform uncussessful SMTP Authentication, and entry is created in the Windows application log;

Web Interface

• Fixed a problem with messages, containing embedded images with same name - was giving Resource already in use error when displaying images;

Mail Server

• In previous versions "stuck" IMAP connections were not getting disconnected, because it was assumed that IDLE command can "stick around" infinitely. It turned out, some clients (e.g., iPhone and iPod) do not use IDLE command, but still leave connections open, which causes open IMAP connections to add up. In this version IMAP connection gets periodically checked, along with POP3 and SMTP connections, and gets disconnected, if it was around for long time, and currently is not in IDLE state;
• Fixed a bug in Archiver: copy function was copying entire folder, not just a selection;
• If a list of trusted or banned hosts contained blank entry, it was returning false positives. Now blank entries are just removed;
• If remoting service cannot start, now it not affect other services.  Before it would crash other services too;
• Added View Log Folder option to the mail server UI;
• Now catching exception when reading server start date/time. It appears, server startup times was not getting stored properly into the Settings.xml file on non-English versions of Windows;
• License is now checked onlny at server startup, rather then during each connection. It appears, decrypting of the license and checking it's signature was taking pretty long time on some systems;

Web Interface

• Fixed a problem with processing MIME messages, when part separators (boundaries) contain space;

• Fixed a potential security threat - no longer accepting very long command lines, which would cause server to crash;

Mail Server

• Fixed long delay when sending mail to large mailing lists, containing large number of local recipients;
• Optimized access to trusted and banned hosts lists;
• Added an option to allow bouncing only to local users (Options - Server Options - Delivery;
• Further optimized resource consuming processes, such as POP3, IMAP and delivery;

Web Interface

• Fixed multiple problems with displaying complex multipart messages;

• Log files now can be stored at the alternate location;
• Fixed a typo in the goodbye message when disconnecting from FTP server (was goodbuy, now - goodbye);

Mail Server

• Outgoing messages would loop infinitely, when there was a DNS server timeout when retrieving MX records;
• Fixed a problem in IMAP, with displaying ? (question mark) sybmols in sender addresses, containing "high" ASCII characters. Would occur only when messages had attachments;
• When deleting users, SQL command timeout increased from 30 seconds to 5 minutes. Was causing SQL server timeout when users had tens of thousands of messages;

Web Interface

No Changes

Mail Server

• Fixed a security issue, which was intrduced in v1.0.6.8 after ading Trusted Senders feature...

Web Interface

• Rich text control now also works with Internet Explorer 8, Safari and Chrome...

• Now transfer buffer size is configurable (Tools - Options - Transfer Buffer Size). In earlier versions it was hardcoded to 32 Kb;
• Fixed a bug when importing data from Win32 version;

Mail Server

• Users, domain groups and mailbags can have individual settings for nine anti-spam features supported by our server. Settings may be inherited from the "above" level, or overriden;
• Added Trusted Senders - you can specify senders (email addresses), and if the value transmitted with RCPT TO SMTP command matches one of them, connection will be considered as trusted. We do not recommend to use this option, we added it for backward compatibility;
• Fixed an Object Reference not Set on Object errors when mail was sent to non-existing domains. This error was not causing any problems, was just showing in the log, causing confusion;

Web Interface

• Made changes to handle individual anti-spam settings (see in the Mail Server sectino above, first point). They are currently handled only for domain group administration section. For list of changes see this document.

Mail Server

• Added Status page to the UI of mail server, now users can see "live" statistics for server;
• Added buffered output to IMAP. It turns out, that some firewalls are corrupting data, if it is sent in small chunks. Buffering allows to avoid these problems;
• Optimized database cleanup procedure at server startup. When DNS cache was large, removal of expired records was causing database server timeouts, and server was not starting up;
• Added status bar to the mailbox viewer, and now message load is performed in a separate thread, which means, screen will no longer freeze when browsing folders containing large number of messages;
• Fixed a bug with UID COPY IMAP command. When copying 1st message, was causing Index of Range errors;
• Fixed a problem with accessing newly created users from web interface, default folders were going to as Shared folders area...

Web Interface

No changes...

Mail Server

• Added support of Shared Folders - now server administrator can create folders, which are accessible for specified users with different levels of rights. Folders can be accessed via IMAP, or web interface;
• Archiver module is no longer a module. It became an integral part of server now;
• Reverse PTR checking option now allows exceptions - specified IP addresses (on top of trusted hosts) will be not checked;
• Fixed a problem with the rotation of DNS servers.

Web Interfacer

• Added support for shared folders. If you have modified web interface, see this document for the list of changes.

May 27 2009, v1.0.1.7

• ZIP and UNZIP SITE commands now use native, fully managed .NET code from DotNetZip library, which replaces older unmanaged, Win32 based library;
• Fixed a bug - if SQL server was not used, then export from the Win32 FTP server was not working.

Mail Server:

• Made a quick fix.5: users, who had global filtering enabled would not receive mail. Please download and install 1.0.6.5, released on May 18 2009 (click Help - About).
• Updated GeoIP database

IMPORTANT: If you are using one of Archiver or AutoWhitelisting optional modules, they also must be upgraded!

Mail Server

• Added PIPELINING and VRFY SMTP extensions;
• Now DSN, PIPELINING, VRFY, SIZE and ETRN extension can be turned on or off;
• Fixed a problem with "hanging" bounced messages, when original messages were included as message/rfc822 attachments, and they were relateively large;
• Fixed a problem with domain group broadcast messages;
• Domain group quotas now are calcucated correctly;
• If .eml files are dropped to user icons on the mail server controller UI, they will be added to user inbox;

Web Interface

• Fixed a problem with viewing messages, containing duplicate parameters in headers;

IMPORTANT: If you are using one of Archiver or AutoWhitelisting optional modules, they also must be upgraded!

Mail Server

• Fixed a problem, which was new in 1.0.6.3 - when adding new users you would get DBNull Cannot be Cast... errors, because new field tracking usage calculation related fields was not being added;
• Fixed a problem with the v0.95 of Clam-AV antivirus. It appears, new version was not interpreting properly DOS style paths, and email files were not getting properly scanned;
• Fixed a problem with domain group quotas - was working properly only when each domain group user also had set domain group quotes;
• Replies to UIDL and LIST commands in POP3 now are getting sent in a "single batch", rather then line by line - significantly improves performance;

Web Interface

• No changes...

IMPORTANT: If you are using the web interface and/or other optional modules, modules you use also must be upgraded!

Mail Server

• Fixed a problem with mailbox usage calculations;
• Fixed a bug with custom bounce messages;
• If during reception, message size exceeds the maximum allowed size, the server will wait until entire message is received (without allocating additional memory), and send back a rejection error message only after sending MTA is done with transmission. In earlier versions server was sending error message without waiting for end, making delivering MTAs assume that there was just a transmission error, and making them to do multiple retries to deliver large messages;
• When checking reverse PTR records, in case lookup fails will assume PTR record does not exist;
• Fixed a problem with Outlook Express in case email addresses of senders contained illegal characters. Outlook Express was just skipping them when accessing a mailbox using IMAP;
• Connectio monitor frequency is now configurable (Options - Server Options - Advanced);

Web Interface

There are no significant changes, but it must be upgraded to keep shared libraries syncrhonized with the mail server;

Mail Server

• Fixed a problem with forwarding messages from the user who uses Junk folder, rather then rejects detected spam to an another user, who does not use Junk folder, now detected junk mail will be rejected;
• The UI was adjusted to handle optional modules;
• Fixed a problem with closed distribution lists, apparently, it was not working properly since last version;
• Made further fixes at the Users, Domains tab of the mail server UI, there was still possible to rename domain groups by clicking nodes on the left panel, and it was causing confusion;

Web Interface

No changes...

Mail Server

• Added antivirus support (Security - Anti Spam - Antivirus). Now you can integrate ClamAV antivirus into the Mail Server .NET
• Added support of Banned Hosts - works the similar way as Trusted Hosts, which have been there from very beginning, and is located under Security - Anti Spam - Banned Hosts.
• Added the way to forward selected messages from server to anywhere to any other user folder, or to external SMTP server, something similar to the Transfer feature in the Pro version;
• Starting from this version, distribution can be "closed" so that only users who have domain group administrator rights are able to send mail to them; Before any trusted connection could send mail to closed lists;

• When running setup (MailServerSetup.msi): if selected installation folder does not match previous installation folder (if previous installation is detected by finding the Settings.xml file in the common application data folder), then the user gets a prompt whether he wants to cancel the setup, and start it over again, selecting the old folder;
• "bare" IP addresses as domain names now are supported (joe@127.0.0.127);
• Changed default values:
  • Options - Server Options - Delivery Options: Delivery Interval Increment now is 2 minutes (was 0);

  • Anti Spam - Security - Greylisting: added domains argosoft.com, aol.com, aim.com to the list of domains for which greylisting will be not required;
  • Greylisting - Initial delay for previously unknown triplet, reduced from 30 to 10 minutes.

We have discontinued our email address validation service, and launched new web site:

http://www.emailaddressvalidator.com

It provides the web service interface to validate lists of email addresses. We hope that our service will help to reduce unwanted traffic on Internet, ensuring that mail is sent only to valid and legitimate addresses.

Sign up now, and get 150 free validations!
